A recent study just came out showing how our heart rate can predict our survival after a heart attack. Basically the slower your heart beats the healthier you are.
The faster your heart beats the more work your heart does. It is working harder, it’s pumping out more blood to keep up with the demand! The better aerobic condition the person is the slower the heart beats. The goal of the beating heart is to transport blood and oxygen to the muscles and every time your heart beats it sends out oxygen with that blood. If you are jogging, working out or shoveling snow you are working your muscles and those muscles need oxygen. Oxygen is carried on our red blood cells….and the more oxygen an individual blood cell can carry the less your heart has to beat. In essence the more efficient your heart functions due to your physical condition.
Think of it like a bucket brigade….trying to put a fire out. If everyone is using a bucket that only carries one gallon of water – you need lots of buckets working pretty fast to put the fire out. But if each bucket carries five gallons of water….you don’t need as many buckets to carry the same amount of water.
The same is true with the amount of oxygen your red blood cells carry, the better physical condition you are in the more oxygen your little red blood cells can carry versus someone who is a couch potato and in poor physical condition. The muscles still need the same amount of oxygen as the conditioned athlete when he or she is working out or shoveling snow. The only difference is that their heart doesn’t have to beat so hard to get as much blood to the area, which means less work for the heart and that is a good thing.
Exercise doubles the benefits…
The benefits of aerobic exercise (walking, jogging, swimming, cycling, etc…) is that it increases the amount of oxygen our red blood cells can carry, which means our heart doesn’t have to beat as much. This is great for anyone struggling with any type of heart condition, but there is another added bonus when you start exercising and increasing the amount of oxygen in your tissues.
The other big plus is that all that oxygen running throughout your body makes it harder for various types of bacteria, viruses, parasites and other pathogens including cancer cells to survive. All these guys strive in an environment that is void of oxygen. So when you start exercising and increasing the amount of oxygen in your tissue you make it a much harder breeding ground for those bad microbes and cancer cells to survive.
A great functional test to determine how efficient your heart is – is performed by measuring how quickly your heart beat drops after revving it up. The goal is to see if your heart rate will drop by at least ten beats after doing an intense exercise. After raising your heart rate to a pretty good rate from some fairly intense jogging, swimming, cycling, etc…see how long it takes for it to drop at least ten points.
This is a great old test that lets us see how well the body recovers. The better conditioned the person the faster it will drop. Prior to the kids coming I could do a 300 yard sprint and my heart rate would drop about 35 beats within one minute of rest. I know there are some people who after intense exertion will only drop a couple of points after a minute recovery. This is not a good sign and a definite signal that their cardiovascular system needs some attention.
Hopefully this opened your eyes for the need and importance of exercise. If you are not sure where to begin or what to do, grab a copy of “To Burn or Not to Burn, Fat is the Question.”It walks you through the rhyme and reason to exercise and what type of exercise would give you the best results.
